TEST
3 Turn the ignition off.
Disconnect the Brake Lamp Switch harness connector.
Disconnect the PCM harness connector.
Turn the ignition on.
Measure the voltage of the (K29) Brake Switch Signal circuit in the Brake Lamp
Switch harness connector.
Is the voltage above 1.0 volts?
Yes → Repair the short to voltage in the (K29) Brake Switch Signal
No
4 Turn the ignition off.
Disconnect the Brake Lamp Switch harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the (K29) Brake Switch Signal circuit at
the Brake Lamp Switch harness connector.
Is the resistance below 5.0 ohms?
Yes → Repair the short to ground in the (K29) Brake Switch Signal
No
5 Turn the ignition off.
Disconnect the Brake Lamp Switch harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the (K29) Brake Switch Signal circuit from the Brake
Lamp Switch harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Go To 6
No
6 Turn the ignition off.
Disconnect the Brake Lamp Switch harness connector.
Measure the resistance between ground and the (Z1) Ground circuit at the Brake
Lamp Switch harness connector.
Is the resistance below 5.0 ohms?
Yes → Go To 7
No
